Lines at the store‚ driving on the highways and how schools classrooms are getting bigger. This is all due to the human population intensifying. We add about a million and half people to our world population every week! What effects is this having on our environment? Is it hurting our water systems and changing our climates? What can we do as a society to help or change

species‚ occupied Earth. By 30‚000 years ago‚ however‚ only Homo sapiens—the most modern species—remained. One of the most hotly debated issues in paleoanthropology‚ the study of human origins‚ focuses on how Homo sapiens evolved to outlive the other hominids. The current best explanation for the beginning of modern humans is the Out of Africa model.

Describing our human origin advances and growth from the beginning of time to today’s time will be explained in nine big eras. Each nine big eras begins and ends in periods of chronological time periods. The first big era started between 13 billion to 200‚000 years ago. This era is about our world in the creation of the environment in which we live in. It is also about the plants and animals that grew in this world too.

laboratory process in which genes from the DNA of one species are extracted and artificially placed into the genes of another organism to produce a desired trait in the plant. Genes may come from other plants‚ bacteria‚ viruses‚ insects‚ animals or even humans. This process uses the “strong” genes in other organisms and implants them in the animal or plant that is to be modified‚ it makes them stronger‚ bigger‚ and a lot better. But‚ can we allow the uncontrolled use of GMOs? If the genetically modified

The Extinction of Baiji The Baiji‚ also known as the Chinese River Dolphin‚ are part of the family Plantanistiade‚ the river dolphin family. They had exsited in the Yangtze River in China for thousand of years. Nevertheless‚ the Baiji was recently declared extinct.

encourages equal sharing in children but not in chimpanzees Humans actively share resources with one another to a much greater degree than do other great apes‚ and much human sharing is governed by social norms of fairness and equity1–3. When in receipt of a windfall of resources‚ human children begin showing tendencies towards equitable distribution with others at five to seven years of age4–7. Arguably‚ however‚ the primordial situation for human sharing of resources is that which follows cooperative

Humans have had the biggest impact on the earth and of all its life support systems since the beginning and its only now when everything’s nearly destroyed that we finally notice that this planet is all we have. The earth has naturally given us and all the other species on earth exactly what we need to survive‚ yet we continue to find new ways to destroy these given resources to make and supply people with things they don’t

Regression As the human race ‘evolves’ and progresses it has created an environment unsuitable for the generations to come. This Darwinist environment promotes the ideals of a ‘dog-eat-dog’ world‚ in which one person’s ambitions are more important than another human being’s. People strive for the ideal life in which money is not an issue‚ so the matter of living comfortably is not a problem. To live comfortably is an idea of life without worry of matters such as starving‚ fiscal responsibility

In “The Case for Animals Rights” which is written by Tom Regan‚ Regan states that animals should have fundamental rights as humans‚ and also be protected from the unnecessary harm. In addition‚ in Peter Singer’s article “All Animals Are Equal”‚ he has the same standpoint as Regan that animals should have the same principles that human received. In contrast‚ in the article “The Case of the Use of Animals in Biomedical Research” by Carl Cohen‚ he supports Regan in his moral theory
