The forests “breathe” by removing large amounts of carbon dioxide from the air and giving off oxygen. It is feared that the loss of rain forests will increase CO2 levels in the atmosphere and result in global warming. Tribes Tribes Why are indigenous people in danger? When the first European explorers arrived in Latin America, they brought with them diseases such as small-pox, measles, and even the common cold. Europeans were used to these illnesses so they didn’t get sick, but indigenous peoples had never been exposed to these diseases before so many of them became sick and died They live what is called a sustainable existence, meaning they use the land without doing harm to the plants and animals that also call the rainforest their home.
Finally, Native Americans did not have a lot of major diseases before Europeans arrived and did not develop the immunity to a lot of the diseases they had in Europe. After Europeans arrived, all of the things changed for the Native Americans. One good thing that came for them was they could trade for new or better goods. Europeans brought things that the Native Americans had never seen before like armor, horses, and foods and could now try and trade for this. Europeans however also brought advanced weapons like guns and they traded for a few but mostly the guns conquered the Native Americans.
The type of pesticide that can affect our environment and health are the chemical pesticides. Even though it has been proven dangerous by scientists the government still allows the use of harmful chemicals on many of the foods we eat. The full health risks associated with pesticides are unknown and most pesticides have never been thoroughly studied for their possible long-term health effects on humans. Everyday humans, plants and animals are exposed to a number of different pesticides, which are harmful to their health. Constant exposure can seriously endanger their physical and mental health.
Furthermore, there are arguments that global warming is not even a threat as assumed by the majority. In this paper I will present many flaws in the Global warming conundrum ranging from Bias to Political issues. What the majority has come to believe might not be the entire truth. So really, which factors contribute to the global climate change and how do these factors impact the earth compared to human activity? Yes, our earth is currently warming up, but who says this is a bad thing?
Dillon Searcy, Social Values and the Environment 465, Confronting Environmental Racism: Voices from the Grassroots. 1993 “Environmental regulations have not uniformly benefited all segments of society” (Bullard, 15). Non-white races such as “African American, Latinos, Asians, Pacific Islanders, and Native Americans” must contend with environmental pollution from “byproducts of municipal landfills, incinerators, polluting industries, hazardous waste treatment, storage, and disposal facilities” (Bullard, 15). “How can environmental justice be incorporated into the campaign for environmental protection? What industrial changes would enable the United States to become a just and sustainable society?
Thus, the chemical enters the natural food chain. A bug would absorb the pesticide, and be eaten by a bird or other insectivore. That animal would then absorb whatever of the pesticide the bug hadn't metabolised or ejected. From there, it would be passed on through the food chain and be spreaded. It is actually not very useful, because although it kils pests, it does not solve the pest problems permanently( Conditions should be changed to end up this problem.).
* 1In western North America, global warming results in reduction of availability of water for ecosystem. This reproductive success of female insectivorous bats. No, climate change will not result in the extinction of species. * 4Evolutionary changes may occur in species to adapt to the climate change and survive. * 3Extinctions of species due to climate change are difficult to detect because there are too many other factors involved in it.
This way of improving foods has been taking place traditionally by just crossing two plants together and hoping that the new traits are taken without any negative ones (543). Since this is time consuming and not as accurate, scientists now just introduce the new genes, or traits, through the plants’ DNA. Genetically Engineered foods, although meant to be helpful, pose many problems by causing environmental hazards, human health risks, and economic concerns. To begin with, one of the problems with engineered foods is that they can become hazardous to the surrounding environment. This unintended harm to other organisms is caused by many factors.
At first we thought that this is a gift from Mother Earth, but we now realize its consequences. Pollution and wastes that are excreted into the environment can yield devastating aftermath that will affect not only Earth, but also humans. After centuries from now, these sources will also be depleted. So we should find recyclable alternatives that are more efficient and cleaner than the traditional sources. Energy sources on Earth is finite, nothing will last forever.
The trading of illegal animals is the third most common illegal trading, the first being drugs and the second being human trafficking. Illegal trading of animals is not very well known because illegal trading of drugs and human trafficking is more known because of the media attention it creates. Not being educated is one of the main reasons that many people don’t actually know that the animals that they have just got are illegal where they live. Much of the global trade in these animals is accounted for by tourist souvenirs, traditional medicine and bush meat. The illegal trade for these accounts is becoming more and more common, and the laws just aren’t providing enough enforcement to prevent and stop the illegal trading of animals.
