Human activities that may affect water ecosystems such as oceans FISHING Reducing the fish communities in rivers and oceans‚ destructive fishing techniques can also cause water pollution and damage to coral and other aquatic life. Destructive fishing techniques involve the use of dynamite or cyanide; trawling in coral-rich ecosystems; bottom trawls that are dragged along the ocean floor‚ also disrupt and damage critical habitats.

to stand for such high oil prices. With the introduction of biofuel in Hong Kong‚ the public can choose biofuels as alternatives to petrol and diesel with lower prices. Since biofuels can be produced from agricultural wastes‚ food wastes‚ and dried manure which are cheap and readily supplied‚ as a result‚ the prices of biofuels become more competitive to petrol and‚ with more choices‚ the public can reduce their reliance on petrol and diesel. Secondly‚ biofuels are more environmentally friendly

materials‚ or compost‚ added to soil before planting gives the soil the boost in nutrients plants depend upon to grow. Fertilizers added later help maintain the nutrients as the plants use them. Various organic fertilizers enhance the soil‚ including manure‚ blood meal and wood ash. Other organic materials‚ such as peanut shells‚ have few beneficial minerals plants can absorb and are best use as a protective covering. Can You Fertilize With Peanut Shells?

The Effects of Meat-Based Diets on the Environment According to study‚ around 2.5 million years ago‚ humans abandoned their vegetarian habits and adopted a more omnivorous diet in the era of the genus Homo. In 1999‚ researchers were not sure whether the bite marks they found on 2.5 million year old animal bones were made by humans or not. Peter Ungar (2003) of the University of Arkansas made an analysis that concluded the bite marks were indeed from the first members of the Homo generation (1)

Shankar Prasad Introduction Organic farming is not a new concept to Indian farmers. Before the Green Revolution‚ during which the chemical fertilisers were introduced‚ Indian farmers used to cultivate crops using natural resources like Farm Yard Manure (FYM)‚ leaves of various plant species‚ animal wastes‚ etc. With the advent of Green Revolution‚ High Yielding Varieties (HYVs) came into existence. In order to utilise the potentiality of the HYVs‚ the use of chemical fertilisers was popularised

The concept of communities offered two major benefits; first‚ defense against enemies that might threaten the community.

Fertilizer (or fertiliser) is any organic or inorganic material of natural or synthetic origin (other than liming materials) that is applied to soils or to plant tissues (usually leaves) to supply one or more plant nutrients essential to the growth of plants. Conservative estimates report 30 to 50% of crop yields are attributed to natural or synthetic commercial fertilizer.[1] Global market value is likely to rise to more than US$185 billion until 2019.[2] The European fertilizer market will grow
