The article “Human Activities that Affect the Ecosystem” by David Weedmark has for purpose to inform us how human activities affect the ecosystem being the water, the air, the land and the life that we share the world with. According to the article, there are few causes that explain how human activities is destroying the ecosystem. The first one that Weedmark mentions is pollutions. He claims that humans are dumping more than 8 million tons of that plastic into the oceans. In consequences,  wildlife in the sea is deeply affected. Indeed, he gives the example of bleach whales that died in 2017 in Scotland because of the amount of plastic it has consumed. The second cause that Weedmark explains is Global Warming. Indeed, according to environmental scientists, CO₂ emissions that come from burning fossil fuels directly affect the planet’s ecosystem. The author explains that the increase of CO₂ in the atmosphere leads to the increase of the Earth’s global temperature which causes the Arctic ice and glaciers to melt and raise the ocean levels. Weedmark continues by informing us how deforestation causes the ecosystem to change. According to him, because our population is constantly growing, farm are also going bigger which mean that we also remove the dwindling of many forests.  Also, he mentioned that deforestation occurs also because of the lumber that human uses to build their houses and to make space for new houses. Consequently, by destroying the forest, human also destroys the habitat of species that lived in them. Weedmark finishes by giving some solutions in order to help reduce harms to the ecosystem. He mentions that recycling, pick up a piece of trash from the street are easy things that humans can do on their daily basis that have positive effects on the ecosystem. Also, on a bigger scale, Weedmark highlights that big project to positively change the ecosystem is a great solution, for example, he claims that The Ocean Cleanup project could clean up half the plastic currently in the Great Pacific Garbage Patch in five years.

I believe that this article is well organized. It gives us a concrete example of how human activities are destroying the ecosystem which helps us understand the real impact that we have on the Earth. But, for the solutions mentioned I would have found more interesting to know what is the long-term solution that human can do to prevent destroying the ecosystem because Weedmark only mentioned what human can do to fix what they have already done but not what they can do to really stop destroying the ecosystem.
