ENVIRONMENTAL PROBLEMS

ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1

In 2006, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood-burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation),followed by solar hot water/heating, which contributed 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.8% of final energy consumption. While there are many large-scale renewable energy projects and production, renewable technologies

Environment

I'd like to present the main issues of our planet and today i'll name 5 of them. These are air pollution, water pollution, endangered animals, deforestation and rubbish. Air pollution Firstly, lets talk about air pollution, which endangeres our life in cities and also the forests near by. Cars and factories blow poisoned gas in the air and it mixes with the oxygen, so the air that we breathe, becomes dangerous to our health. The ozone layer around the Earth, there

Water pollution and society

Water pollution and society This essay is about fresh water and pollution. It's based on an article by David Krantz and Brad Kifferstein. I read it through and now I'm trying to give the conclusion of the article as well as express my own opinion. 70 percent of planet Earth's surface contain water. Water is the beginning of life and vital natural resource. It's vital for every living organism. That's why we have to keep the water bodies clean and stop polluting our fresh water. It's hard to believe, but planet Earth is in great danger. People can't see the whole picture. They are being indifferent to the future. Everyone thinks about themselves and tries to find a better and easier way to get rid of garbage and waste. Money is everything for them. Money talks and nobody cares about giving a dollar to save the nature. Usually a person thinks that what difference can he make. But if everybody think so,

Human overpopulation

• Human population has been rising continuously since the end of the Black Death, around the year 1350 • The most significant increase has been since the 1950s, mainly due to medical advancements and increases in agricultural productivity • The recent rapid increase in human population over the past three centuries has raised concerns that the planet may not be able to sustain present or future numbers of inhabitants. Loss of Fresh Water • Most of the freshwater resources are either unreachable or too polluted, leaving less than 1% of the world's freshwater, or about 0.003% of all water on Earth, readily accessible for direct human use. • According to the Global Outlook for Water Resources to the Year 2025, it is estimated that by 2025, more than half of the world population will be facing water-based vulnerability and human demand for water will account for 70% of all available freshwater.

We Do Not Inherit the Earth From our Ancestors; We Borrow It From Our Children

We Do Not Inherit the Earth From our Ancestors; We Borrow It From Our Children Some of the people think that the Earth is like something, that we can take and it will grow back like apples every summer on trees. But I do not think it does. I think we borrow it from the future. Firstly we are using too much water nowadays. We are wasting it and not thinking about the future, but we should. Lately the media has started to speak more about the need for clean water, specially in some parts of the Earth. In the past people did not have showers or baths, toilets with water, dishwashers. These and many other things use more water, than people used to. Secondly we are producing a lot more, than we maybe should. It seems like the most meaningful thing nowadays is money. Maybe because of that we are over producing. If we look at the landfills we can see how full they are. I think it is that way because we produce too much and use too much packages

Water

Water Imagine, it is a hot summer’s day, you are walking down the street, the sun is burning your skin, you have been walking quite a while now and suddenly, you feel you are thirsty. So what would you do …. Probably you go to the nearest store down the street and buy a bottle of water; a bubbly water, a vitamin water, a water from the fridge, there is so many variety of waters and still you have something to complain about how the water is to expensive how the day is too hot, how the water is too cold . And now imagine… imagine the people, who live in African deserts, imagine feeling thirsty and not having any water at all, not around you, not anywhere. People who live there they have to make long journeys or treks over rough and barren land to get water and when they finally reach to that hole in the ground, then that water there isn’t even clean. It takes so much
