What percentage of Earth's surface is covered by water?

According to some figures, the consensus is that 70.8% of the Earth's surface is covered by water; 29.2 % is covered by land. Other figures suggest the percentage of Earth's surface covered by water is 71.11%; the percentage covered by land is 28.89%. Only 3% of that water is fresh water, the rest is saltwater. The amount of Earth covered by water is exactly 71.13% 70.78% of the Earth is covered in water. Land covers 29.22 percent of the Earth's surface. This is...

What is the greatest environmental problem today?

Global warming. Our weather is changed and this changes how we live and what we grow. The oceans are rising and coastal areas are flooding. The ice caps are melting and polar bears are drowning. The massive forest fires that now happen threatens cities, houses, and national parks. We are getting to a tipping point of no return if something is not done. ...

What is man's adaptation to environment?

Well, when humans change to make themselves comfortable in unpleasant conditions it is known as adptation or evolution. _____________________________________________ Evolution only occurs when the last species dies and a new one, with a more equipped body, takes over. I refer you, instead of mass spamming the edit box with information, to this very interesting article/essay on the biological adaptation with humans in reference to nutritional, physiological and psychological terms. http://onlinelibrary.wiley.com/doi/10.1111/j.1749-6632.1961.tb31093.x/pdf the geographical variability of some morphological, physiological and serological traits of man is discussed with respect to...

They affect the environment lots of ways, for example, building a skyscraper where you can plant a tree can definently affect the environment or a controlled demolitions can cause debris and dust take away some fresh air. If we build up rather than out, thereby increasing the population density of an area, some of the effects are: (1) Land is available for use other than housing the people who live or work in the skyscraper and for businesses that are quartered there. (2) Some...

What are the problems of rainwater harvesting?

If you own a water utility, you bring in less revenue if your customers begin catching and re-using rainwater. Dirt and leaves fall on your roof and this is washed into your pipes at the first rainfall. This can be fixed with a "first flush diverter" which catches the dirty water automatically. A float rises in a tube as the tube fill with dirty water. When the tube is full, clean water is automatically diverted into your tank. ...

Why not dispose of nuclear waste on the moon?

There are two major problems with this. The first takes the pragmatic view of this option and the other aesthetic. Even in 2010, a jump to the moon is nothing to trifle at. It still takes time, it still takes resources, and more importantly, it still costs money (and a lot of it). But that's not even taking into account the waste you would have to transport. Nuclear waste is going to be heavy, meaning you need a bigger rocket, more...

Asked in Environmental Issues, Radioactive Waste

How do nuclear wastes affect the ecosystem?

Nuclear waste is not normally allowed to enter the ecosystem for many obvious reasons. The correct containment of high level waste is still debated because of this issue. The material will remain radioactive longer than any civilization has ever existed and the concern that the material remains safely away from the ecosystem is very real and hard to quantify. If high level waste does reach the ecosystem, the affect is overall very negative. Animals can become ill or die. Tumors and cancers can...

How does rubbish affect animals?

There are many ways in which rubbish can affect and be harmful to animals. They can get stuck or trapped in rubbish such as old fishing lines, plastic bags and fishing nets. Some eat the rubbish (like sea turtles eat plastic bags because they think it is jellyfish), and then eventually die as the rubbish blocks airways or gets into their stomach and then they are unable to process food. Old cans, and tins can rust and pollute the water, and...

Is there such thing as a solar powered phone?

I have seen cell phone batteries with solar cells in them, but not in a while. So solar powered phones exist. There is also a pocket-sized product called Solio which opens up into a fan of solar panels and contains a backup battery and power charging cords for cellphones. You just have to remember to leave it in the sun while talking on the phone, since there probably isn't much sunlight in your pocket. (It also comes with a plug-in charging cord,...

Asked in Environmental Issues

Are krill considered renewable or nonrenewable?

Whether krill is a renewable or nonrenewable source is a subject of some controversy. Krill harvesting is controversial because it (especially Euphasia superba from the waters of the Antarctic) is at the bottom of the food chain and the main diet of many species, including whales and penguins. The treaty organization that manages the Antarctic fisheries (Commission for the Conservation of Antarctic Marine Living Resources, or CCAMLR) sets "precautionary limits" on the amount of krill that can be caught in any time period, upon...

Asked in Environmental Issues, Rain and Flooding, Natural Disasters

Which are the most vulnerable homes during floods?

MOST VULNERABLE HOMES 1. Buildings, which are constructed with earth-based materials or using stone and brick in mud mortar are highly vulnerable to damage in heavy rains and/or floods. 2. The huts made from biomass materials like bamboo, leaves, thatch or light construction using metal sheets are easily destroyed in floods and washed away. 3. The occupation of areas within the flood plain of rivers has increased the vulnerability, especially in areas of high population concentration. Flood plains attract poor people because of inexpensive land values. ...
