Plastics- boon or a curse

Plastics role in our life:

Today, it is may be a little difficult to imagine our life without plastics. 

Plastics are use in Toys, bags, combs, bottles, water pipes, electrical wires, pens, pots, helmets, airbags in automobiles, they are use in cell phones, computer, laptop, which makes modern life easy, also use in electrical equipment etc.

Problems arises when we use plastics excessively and are ignorant about ways of disposing of their waste.

Impact of plastics on nature :

 

1.All kinds of plastics give out harmful gases, upon heating and burning. These gases may cause many health problems, like cancer and asthma in humans.

2.Consuming food stored in plastic bags could be harmful to our health.

When people fill garbage in plastics and polythene bags and throw it away. When stray animals like cow look for food in these bags, they end up swallowing these and they die due to this.

3.The plastics bags thrown away carelessly on roads and other places get into drains and the sewer system. As a result, drains get choked and the water spills on the roads. During heavy rains, it might even create a flood like situation. In Mumbai, during one or two days rain, roads become choked with water and people suffer with it.

4.Plastics are non biodegradable and we cannot decompose because it can take 20 to 500 years to decompose. 

How to minimise over use of plastics:

1. Reuse the bags whenever it is possible to do so without any adverse effects.

2.We should cloth or jute bag when  we go out for shopping in market.

3. We insist shopkeepers use paper bags.

4.Don't use plastic bags to store eatables.

5.We never burn polythene and plastic bags.

6. We always recycle paper.

7. We don't put garbage in plastic bags.

8. Aware your friends, neighbours and relatives to follow proper practices for disposing different types of wastes.

Reduce means to minimise the amount of waste we create. Reuse mans to using items more than once.

Recycle means convert the product in new use instead of throwing it away.

Need of conserve water

• Ocean and sea water can also fail your kidney.

Rain water harvesting : 

 Rooftop rainwater harvesting: 

In this system, we collect rainwater from the rooftop to a storage tank, through using pipes.This water may contain soil and dust of roof and need filtering before it is used for any purpose. Instead of storing water in tank, we can go directly in the pit in the ground. This then seeps into the soil to recharge the ground water.
