Question

How do artificial fertilisers & pesticides affect wildlife?

Answer 1

pesticides and herbicides are wrong all the time as well as fertilizers

they kill plants and     insects they are  not suposed to kill,or  fish in therivers

they contaminate ground waters ,raise the PH and affect human childbirth very negatively.

And desertification is usually the final product when the soil has been killed by agro chemicals and heavy equipment

Alternative Farming Methods ,that are sustainable and autosufficient ,using proved organic methods are the answer

there are hundreds of ways to get rid of pests either by design (diversity)or organic methods of pest control

herbicides are rediculous

just a mulch cover gets rid of weeds and produces compost this also makes fertilizers obsolete

MULCH

what you do is to cover the ground with mulch which is the same principal as compost but it includes the whole garden surface

the top part of the soil where the topsoil is being produced houses a world or microbiotic life.

Mulch is organic material green or dry that covers the ground,the thicker the better the composting process will turn it in to black topsoil

the humidity is preserved underneath and promotes the devellopment of worms,who airate the soil (their exists no better compost than their excrements)and a variety of micro biotic life which together with the mulch produce more topsoil.

the mulch also keeps the ground temperature even and guards against the impact of the rain ,which would other wise brings salt to the surfave if on unprotected land

Mulch also prevents the soil from drying out because of the sun and, lay it open to wind erosian.

and it turn out the lights for any weeds that want to come up

do not use chemicals because the water will wash them into the ground and if enough people did that, you would be guilty of helping to contaminate subteranean water suplies that other people could be pumping up to drink,

ALTERNATIVE FARMING

read up on Organic Farming and Permaculture

A lot of hardcore Intelligent farmers are changing for sustainable farming

instead of the quick 3 to 5 years of intense monocultures that kill the ground and then live with the consequences

and dont talk dirty again,mentioning pestecides and herbicides , there are childen on this show

NOTE ON ORGANIC PEST CONTROL

Just a few examples of organic pest control and there are thousands

In Mexico we got a sort of small lizard that lives on the wall ,and sit near the lamps ,and eat mosquitos all night,

in the mango orchards we release laboratory bred wasps to attack and kill the caterpillars that go for the mangos

there are small chickens, called a silky or bantom or chaparito which are all small chickens that do not scratch ,but run after ,jumping and walking insects,they take care of about 70 percent of all garden pests.

feasants,guinyfowel,partridge will do the same work

iguanas kill grashoppers and all kinds of flying insects

birds we also dont kill

when the passion fruit is ripe ,a little black caterpiller comes and wants to destroy them,luckely a little finch type bird turns up and eats the black caterpillars.

In Mexico we have let mazacoas,which are, python type snakes in to the garden to take care of the rats.

In Africa we released mole snakes into the garden and field to combat the plagues of Norwegian rats that were destroying the fields

ant eaters and armadillos take care of leafcutting ants that can destroy a large tree in a week.and eat beatles and such

potbelly pigs and deer and normal pigs are good in an orchard because they eat fallen rotting fruit which breeds a lot of small flies.

in our water reservoirs we put fish to eat the mosquito larvas.

i have bred tree frogs from eggs and released them in the garden to eat mosquitos and horse flies.

Permaculture is a world recognised earth friendly movement but tends to include people that practice the concept and is active in all fields

Permaculture means permanent agriculture

a concept put forward by Bill Mollisson in the 60`s

With practical solutions for energy systems ,infrastructure ,housing,

animal shelter ,water systems and sustainable agricultural practises.

Answer 2

I work with surface water, so that is the aspect I know the most...

Fertlizers can dramatically affect surface water, by increasing the nutrient load, causing algae to grow out of control in the waterway (anytime you see brown or green stuff in the water, that water body may have a nutrient problem). The algae uses all the oxygen in the water and suffocates fish and bugs, killing them. Algae can also physically fill a waterbody so that wildlife can't get to it. (I counted fish as wildlife).

Pesticides can directly harm wildlife by poisoning them (contact with spray drift, contact from recent sprays, contact from water that has been poisoned by drift of runoff). Pesticides can also kill bugs and plants that the wildlife are depending on for food, therefore starving them. Pesticides do not kill/harm just their target pests unfortunately, and so water, air, and food supply can all harm wildlife which are at the top of the food chain generally.

Answer 3

The artificial fertilisers do not affect the wildlife directly, imbalanced use of such fertilisers affect the fertility of the soil.

Whereas the pesticides affect directly to the wildlife, by the consumption of the pesticides directly or indirectly, it cuase hiphertention and others. R.S.CHOUDHARY
