THE EARTH IS PRECIOUS The earth gives us life and many things which we need in our daily life‚it provide us with natural resources which is mostly needed for humans and technology.But perhaps our planet is in great danger. For the last one hundred or so years‚ the people of earth have wasted and misused the natural recourses of earth. Several plans have been developed to stop the abuse of earth in which many of them can be executed by any one. Environmental problems have become so complex that many

different forms of global pollution that may arise from a construction project and explain four key methods used to protect the natural environment against such pollutants Environmental Pollution Construction Sites Construction sites are found both within urban and rural areas‚ often in the close proximity of homes. Due to their proximity to homes and the materials used‚ construction sites may generate home pollution. This involves air‚ water‚ soil‚ and/or noise pollution. Additionally‚ construction

• Forests Forests is not just made of trees but also animals and micro-organism. Throw into the mix the non-living‚ abiotic components like soil‚ climate and water‚ and take in the complex interrelationships among the organisms and the environment‚ and we are closer to an actual understanding of this ecosystem. With one third of the Earth’s surface is covered with forests it is no surprise that they are among the most notable storehouses of biological diversity on the planet. Forests have a

I’m glad I was able to push myself to get to that point! It was my mission to change everything about me‚ that I could change with exercise. Whenever I started talking to people about it‚ they talked as though it was impossible to do. I couldn’t believe what I was hearing. I knew that couldn’t be right! That caused me to research my theory‚ to see if it was true. Once I was able to find information that supported my theory‚ I started to create a plan to get my desired result. I stood in the

EARTH SURFACE REALMS 2And3 We can look at Earth’s surficial "layers" as being comprised of several major realms or "geospheres": the atmosphere‚ lithosphere‚ hydrosphere‚ biosphere and pedosphere. The reference to "sphere" applies because Earth is spherical‚ and hence layers around it form somewhat spherical shells at the outermost edges of the solid planet. The atmosphere‚ biosphere and lithosphere more completely encircle Earth‚ while the hydrosphere and pedosphere tend to be more discontinuous

Marine Pollution Marine Pollution is a major problem that is among issues of discussions around the world today. There is an increasing awareness made‚ especially across the Asia and pacific region these days. This problem is a major concern because the marine environment is a dumping ground of unwanted waste materials. This has initiated dialogue to mobilize careful considerations in strategies of overcoming this problem. This essay will argue that marine pollution should be addressed immediately
