The world's oceans and coastal ecosystems can store remarkable amounts of carbon dioxide. But if they're damaged, they can also release massive amounts of emissions back into the atmosphere.

Like many other plant-based foods and products, CBD oil is one dietary supplement where "organic" labels are very important to consumers. However, there are little to no regulations within the hemp industry when it comes to deeming a product as organic, which makes it increasingly difficult for shoppers to find the best CBD oil products available on the market.

The company is currently in the process of achieving official USDA Organic Certification, but it already practices organic and sustainable cultivation techniques to enhance the overall health of the soil and the hemp plants themselves, which creates some of the highest quality CBD extracts. Charlotte's Web offers CBD oils in a range of different concentration options, and some even come in a few flavor options such as chocolate mint, orange blossom, and lemon twist.</p>

The year 2050 has been predicted by some to be a bleak year for the ocean. Experts say that by 2050 there may be more plastic than fish in the sea, or perhaps only plastic left. Others say 90% of our coral reefs may be dead, waves of mass marine extinction may be unleashed, and our seas may be left overheated, acidified and lacking oxygen.

Trillions of barely visible pieces of plastic are floating in the world's oceans, from surface waters to the deep seas. These particles, known as microplastics, typically form when larger plastic objects such as shopping bags and food containers break down.
Solving the Plastics Puzzle<p>It's not news that wild creatures ingest plastic. The first scientific observation of this problem came <a href="https://doi.org/10.2307/4083505" target="_blank" rel="noopener noreferrer">from the stomach of a seabird in 1969</a>. Three years later, scientists reported that fish off the coast of southern New England were <a href="http://dx.doi.org/10.1126/science.178.4062.749" target="_blank" rel="noopener noreferrer">consuming tiny plastic particles</a>.</p><p>Since then, well over 100 scientific papers have described plastic ingestion in numerous species of fish. But each study has only contributed a small piece of a very important puzzle. To see the problem more clearly, we had to put those pieces together.</p><p>We did this by creating the largest existing database on plastic ingestion by marine fish, drawing on every scientific study of the problem published from 1972 to 2019. We collected a range of information from each study, including what fish species it examined, the number of fish that had eaten plastic and when those fish were caught. Because some regions of the ocean have more plastic pollution than others, we also examined where the fish were found.</p><p>For each species in our database, we identified its diet, habitat and feeding behaviors – for example, whether it preyed on other fish or grazed on algae. By analyzing this data as a whole, we wanted to understand not only how many fish were eating plastic, but also what factors might cause them to do so. The trends that we found were surprising and concerning.</p>
A Global Problem<p>Our research revealed that marine fish are ingesting plastic around the globe. According to the 129 scientific papers in our database, researchers have studied this problem in 555 fish species worldwide. We were alarmed to find that more than two-thirds of those species had ingested plastic.</p><p>One important caveat is that not all of these studies looked for microplastics. This is likely because finding microplastics requires specialized equipment, like microscopes, or use of more complex techniques. But when researchers did look for microplastics, they found five times more plastic per individual fish than when they only looked for larger pieces. Studies that were able to detect this previously invisible threat revealed that plastic ingestion was higher than we had originally anticipated.</p><p>Our review of four decades of research indicates that fish consumption of plastic is increasing. Just since an international <a href="http://www.gesamp.org/publications/microplastics-in-the-marine-environment-part-2" target="_blank">assessment conducted for the United Nations in 2016</a>, the number of marine fish species found with plastic has quadrupled.</p><p>Similarly, in the last decade alone, the proportion of fish consuming plastic has doubled across all species. Studies published from 2010-2013 found that an average of 15% of the fish sampled contained plastic; in studies published from 2017-2019, that share rose to 33%.</p><p>We think there are two reasons for this trend. First, scientific techniques for detecting microplastics have improved substantially in the past five years. Many of the earlier studies we examined may not have found microplastics because researchers couldn't see them.</p><p>Second, it is also likely that fish are actually consuming more plastic over time as ocean plastic pollution <a href="http://dx.doi.org/10.1126/science.aba9475" target="_blank" rel="noopener noreferrer">increases globally</a>. If this is true, we expect the situation to worsen. Multiple studies that have sought to quantify plastic waste project that the amount of plastic pollution in the ocean will <a href="http://dx.doi.org/10.1126/science.aba3656" target="_blank" rel="noopener noreferrer">continue to increase</a> over the <a href="http://dx.doi.org/%2010.1126/sciadv.1700782" target="_blank" rel="noopener noreferrer">next several decades</a>.</p>
Risk Factors<p>While our findings may make it seem as though fish in the ocean are stuffed to the gills with plastic, the situation is more complex. In our review, almost one-third of the species studied were not found to have consumed plastic. And even in studies that did report plastic ingestion, researchers did not find plastic in every individual fish. Across studies and species, about one in four fish contained plastics – a fraction that seems to be growing with time. Fish that did consume plastic typically had only one or two pieces in their stomachs.</p><p>In our view, this indicates that plastic ingestion by fish may be widespread, but it does not seem to be universal. Nor does it appear random. On the contrary, we were able to predict which species were more likely to eat plastic based on their environment, habitat and feeding behavior.</p><p>For example, fishes such as sharks, grouper and tuna that hunt other fishes or marine organisms as food were more likely to ingest plastic. Consequently, species higher on the food chain were at greater risk.</p><p>We were not surprised that the amount of plastic that fish consumed also seemed to depend on how much plastic was in their environment. Species that live in ocean regions known to have a lot of plastic pollution, such as the Mediterranean Sea and the coasts of East Asia, were found with more plastic in their stomachs.</p>
Effects of a Plastic Diet<p>This is not just a wildlife conservation issue. Researchers don't know very much about the effects of ingesting plastic on fish or humans. However, there is evidence that that microplastics and even smaller particles called <a href="https://doi.org/10.1038/s41565-019-0437-7" target="_blank">nanoplastics</a> can move from a fish's stomach to its <a href="https://doi.org/10.1016/j.scitotenv.2019.134625" target="_blank">muscle tissue</a>, which is the part that humans typically eat. Our findings highlight the need for studies analyzing how frequently plastics transfer from fish to humans, and their potential effects on the human body.</p><p>Our review is a step toward understanding the global problem of ocean plastic pollution. Of more than 20,000 marine fish species, only roughly 2% have been tested for plastic consumption. And many reaches of the ocean remain to be examined. Nonetheless, what's now clear to us is that "out of sight, out of mind" is not an effective response to ocean pollution – especially when it may end up on our plates.<br></p><p><em><a href="https://theconversation.com/profiles/alexandra-mcinturf-1205082" target="_blank">Alexandra McInturf</a> is a PhD Candidate in Animal Behavior at the University of California, Davis. <a rel="noopener noreferrer" href="https://theconversation.com/profiles/matthew-savoca-313547" target="_blank">Matthew Savoca</a> is a Postdoctoral researcher at Stanford University.</em></p><p><em>Disclosure statement: Alexandra McInturf is affiliated with <a href="https://theethogram.com/" target="_blank">The Ethogram</a>.
