water‚ among others. Fire had been used since early humans ruled the land to keep them warm at night and defend them from wild and dangerous animals. Modern humans who have the ability to think efficiently have harnessed the power of the wind in transportation and even in generating energy. And electricity had been used to power up every machine used in different human activities. However‚ there are still a lot of things in nature that the humans had not fully understood and had not enjoyed. Instead

Animal extinction is happening nowadays due to the multiple factors of environmental degradation. The primary cause of environmental degradation is human disturbance. Extinctions caused by human are generally considered to be are recent phenomena. When humans convert wild areas for agriculture‚ forestry‚ urban development‚ or water projects including dams‚ hydropower‚ and irrigation‚ they reduce or eliminate its usefulness as a habitat for the other species that live there. The temperature of the

A multitude of species have vanished in the five cataclysmic mass extinctions‚ and as of today‚ about 99.9 percent of all species that have existed on Earth are extinct. These five extinctions were the Ordovician-Silurian extinction‚ the Late Devonian extinction‚ the Permian-Triassic extinction‚ the End Triassic extinction‚ and the Cretaceous-Tertiary extinction. They wreaked havoc on more species than you could imagine‚ and if you think today that there are a lot of species‚ imagine if the five

Amphibians are becoming a vanishing species. There are a number of causes for them dieing. But the most recent and worst cause has been discovered. It is responsible for killing off our amphibians. They are dieing by the thousands. They were able to survive and hold on through past extinction spasms‚ surviving even when 95 percent of other animals died out. They even stayed alive when the dinosaurs disappeared. If amphibians could live longer than dinosaurs‚ then why are

helped large species such as the mammoth‚ bison‚ deer and all their relatives to cross over to the Americas. The ancestors of the human species made its big appearance‚ but most importantly there was the catastrophic extinction event of many species near the end of the Quaternary period. The event had a great effect on the species roaming on Earth. The Quaternary extinction event was caused by factors such as global climate fluctuations which pushed many to adaptation and others to extinction. It’s also

Some people say human activity makes the Earth a better place to live. But actually as we want more comfort and fancy life‚ we are actually damaging the Earth. There are three general ways to harm the Earth‚ Air‚ Soil and Ocean and we are damaging all three of them. Firstly‚ we ride our cars to go somewhere. In my opinion‚ cars are mainly responsible for air pollution. Air pollution is one of our most serious problems because we breathe everyday and even animals and plants need clean air. We all

Biodiversity has been on the decline over the past century and the background rate has been mostly accelerated by the humans. Considerable damage has already been done. Possible solutions have been discussed and categorising species according to how in danger they are is one of those solutions. Below are some of the threatened organisms in different continents around the world. TABLE OF CONTENTS Africa Mammals Birds Reptiles Amphibians Fishes Asia Mammals Birds Reptiles

The invasive species are harmful for native systems and time and money should be invested to prevent these species from spreading and damaging systems that they are not native to. Strict rules for environmental obedience are necessary and good. Much more needs to be done to protect our planets and its biodiversity from the invasion of alien species. When non-native species from other ecosystems are introduced‚ they can upset that balance and bring harm to the established plants and animals‚ and

It also answers inquiries of; is it a major contributor to climate change? Do I agree or disagree? From my research and readings‚ I‘ve concluded that‚ the foremost effect that burning fossil fuels has on our environment is the greenhouse effect‚ also known as global warming. Carbon dioxide‚ which is also known as greenhouse

There are many endangered animals in the world today‚ which play important roles in our environment and in our lives. Humans are the main cause of these animals becoming extinct‚ but with the help of the government and caring people some of these animals have increased in numbers and have been taken off the endangered species list. Many people think that they cannot do anything to help these poor animals‚ but they are wrong. There are many ways in which people can help to keep these animals from
