The Earth is dangerous place than ever. The reports of natural disaster occurring constantly with intensity. We, the human beings are the one that changed the world. This creates a situation in which ordinary events like earthquakes and hurricanes become increasingly elevated to the level of natural disasters that cause heavy losses in human life and property. The earth is warming. Earth’s average temperature has risen by 1.4F over the past century. This has affected the worlds climate and the ecosystem we live. Many places have seen changes in rainfall, resulting more floods, drought, or intense rain as well as more frequent and severe heat waves. Oceans are warming and becoming more acidic, ice caps are melting and the sea levels are rising.…show more content…
The natural disasters are storms, floods, tropical cyclones, local storms, heat and cold waves, wildfires and droughts. The geographical disaster are classified as volcanoes, dry rock-falls, landslides and avalanches. In 1970, the number of natural disasters that were reported was 78 whereas in 2004, the number of disasters jumped to 348. According to AccuWeather, since 1990, 217 million people were affected by the natural disasters. From 1980 to 2009 there was an 80 percent increase in disasters related to climate change. Between 2001 and 2010, more than $1.2 trillion was lost due to the natural disasters. This was a dramatic rise, which between 1981 and 1990 it had only been about $528…show more content…
An ecosystem includes all of the living things such as plants, animals and microorganism in a given area, interacting with each other, and also with their non-living environments. For example weather, earth, sun, soil, climate, atmosphere. Ecosystems provide us with food, medicines, and many other goods. In an ecosystem, each organism play a vital role in nutrient cycling, water purification, and climate moderation.

Climate change will affect wildlife ecosystems and the habitats that support life from oceans, grasslands and forests. Climate change can have huge effects on the number and variety of plant and animal species around the world. Although species have adapted to environmental change for millions of years, a quickly changing climate could require adaptation on larger and faster scales than in the past. Those species that cannot adapt to the new environment are at risk of extinction. Even the loss of a single species can have hazardous effects because organisms are connected through food chains and other interactions. The oceans and the atmosphere are constantly interacting, exchanging heat, water, gases. As the atmosphere warms, the ocean absorbs some of this heat. The amount of heat stored by the ocean affects the temperature of the ocean both at the surface and at great depths. Warming of the Earth’s oceans can affect and change the habitat and food supplies for many kinds of marine life—from plankton to polar
