We all know that cancer itself is a bad thing. Every day, people are always trying to find ways to prevent and treat cancers in humans. What we don't realize, however, is that all our human activities to make our lives more comfortable are killing the spices and animals that need these resources. We are not just hurting animals, but the planet itself. Such factors would be global warming and the food we eat. If we don't change our behavior soon, the earth will die from what they call "human cancer". The end of the earth will be caused by human cancer because we only think of ourselves before we start doing activities that harm the planet. Illegal poaching is a major factor in this. Even if we look good in our fur and animal-based clothing or the nice decorations in our home, we are endangering those animals. Poaching is a crime that is overlooked in many places, which is why so many animals are currently suffering. Say no to plagiarism.

Get an original essay One of the main reasons why poachers continue to do what they are doing is the fact that they could make a lot of money from it. By killing these animals, you put more funds in their pockets, so obviously why shouldn't they continue to earn good money? According to Massimo Giangaspero, “The gallbladders of bears fetch top dollar for Chinese herbal remedies, and the horns of bighorn sheep can fetch $20,000 on the black market. Therefore, for many poachers, profit is the main motive.” Even though there is a ban on the international ivory trade, unfortunately African elephants are still poached in large numbers today. Thousands of elephants are killed every year for their ivory tusks. Ivory is often carved into decorations and jewelry. China is the main sales market for these products. Rhino horn is a highly valued form of traditional Chinese medicine, practiced in China and parts of East Asia. Every year many rhinos are killed illegally for their horns. If animals continue to be used and seen as money, there will be no more left, which would lead to humans who depend on poaching falling into drought. Also, we use them for food, so using them the wrong way will ultimately harm us. Sooner or later we will no longer have the meat of these animals to eat to keep us alive. Animals have more value on the planet than humans give them. Another factor in human cancer in the future is what is currently in our food. Farmers put different types of hormones into their animals for production and when we eat those animals we get harmful chemicals that enter our bodies. Hormones can allow new animals to gain weight more quickly. They reduce the waiting period and total food consumption by an animal before killing in the meat industry. For example, putting hormones into new cows can make them gain heaviness more quickly. Extra heaviness leads to extra meat, which means extra money for the producer. Hormones also increase cows' milk production. Once again, humans use animals in a way that benefits them without feeling sympathy for them. Hormones and steroids in animals are not healthy for them or for humans. Studies have shown that these hormones increase the risk of breast cancer, prostate cancer, and other cancers in humans. According to Carina Storr“In a 2004 study, patients with higher-than-average IGF levels had a nearly 50 percent greater risk of prostate cancer and a 65 percent greater risk of hormone-dependent premenopausal breast cancer than people with high levels. below average." Although drinking milk and eating various dairy products have been shown to increase blood levels of human IGF, the increase is perhaps not the exact result of the animal's IGF level or the IGF discovered in foods. This is because the total IGF in dairy crops, whether it comes from cows preserved with rBGH, contrasts with what the body naturally has. Additionally, as a type of hormone produced by our body and critical for the normal growth of healthy tissue, artificial steroid hormones used as medications have been found to influence cancer risk. For example, diethylstilbestrol, an artificial estrogen drug used in the 1960s, was withdrawn from use once the high risk of vaginal cancer in the daughters of treated women was discovered. Having these chemicals in the body is literally causing cancer in humans, and as we know, there is currently no cure for cancer. We are also killing ourselves by consuming these hormone based animals that have left chemicals in the foods we eat. Overfishing occurs when people go fishing and catch more fish than the population can replace through natural reproduction. Harvesting as much fish as possible may seem like a money-making habit, however overfishing comes with very significant penalties. The consequences not only affect access to life at sea, but also the social and economic satisfaction of coastal groups that depend on fish for their livelihood. Fish is the main food the world relies on for protein. For many periods the sea was thought of as a boundless reward in terms of food. However, increasing fishing attempts over the past 50 years and unsustainable fishing habits are bringing many fish quotas closer to the point of failure. At least 30% of the planet's fisheries are deficient outside their genetic limits and require stringent management plans to restore them. Numerous significant money-making fish populations have refused to the point of endangering their existence as a species. According to RJ Beamish “Growth growth overfishing occurs when fish are caught at too young an age so that individuals reach only a small percentage of their growth potential. Overfishing and recruitment reduce the spawning stock to such a level that the number of juveniles is unable to replenish the population." Overfishing puts fish in danger of extinction and in the meantime they cannot replace themselves as quickly as they are caught, the sea will eventually be emptied of fish. The main source of protein that humans rely on is slowly disappearing and if we don't reduce fishing activities there will be none left. This also contributes to “human cancer” and the death of the earth because we need fish in the ocean but humans are taking advantage of them instead. We literally share everything on Earth with all living things in the world, what happens in a single part also affects everything, regardless of distance. Pollution has negative results on the ecosystem we depend on. We emit different types of elements into the air when we burn the fossil fuels found in our daily lives. Emily Beach said: “Polluted air is linked to a range of health problems, ranging from short-term irritation to serious illness or even death. Much of the pollution.
