Class 5 Science notes- Changes in Our Environment
The environment and its natural resources have to be conserved for our own needs and for future generations. Special efforts have to be made to reduce the process of global warming. But this is easier said than done. Government alone will not help. All of us should realize how important it is to protect the environment.
Our government has taken some steps to reduce pollution and preserve the natural environment. Some of them are discussed here.
- Research on the utilization of solar energy is being encouraged as it does not cause any pollution. The government is also subsiding solar coolers, solar water heaters, etc., to make popular.
- At some places, factories are being shifted away from the main city. Also, factories are being asked to convert harmful substances into harmless ones before releasing them. There has also been a ban on throwing industrial wastes into water bodies.
- Planting of trees is being encouraged. Every year, July 1 is observed as the VAN MAHOTSAVA day. On this day, trees are planted on a large scale.
- Farmers are being encouraged to use natural fertilizers. These provide better yields and environment -friendly.
- In Delhi, some major steps have been taken to check air pollution. Catalytic converters have been made compulsory in cars. These converters change harmful gases into harmless ones. All buses now run on non-polluting CNG (Compressed Natural Gas). All commercial vehicles that are more than 15 years old are not allowed to run on the roads.
