Experts call to revisit ban on Plastic in Tami Nadu

The government of Tamil Nadu on World Environment day 2018 on 5th June had announced that it would ban the use of plastic items, including non-biodegradable bags, from January 1, 2019, with some exceptions. Plastic was allowed only for only milk, oil, medicine packets and other items of basic needs.

The ban was announced by the Chief Minister under Rule 110 of the state Assembly which allows the chief minister to make announcements without a debate in the House.

Why calls to revisit the decision of ban on Plastics?

Those demanding a revisit argue that

  • Elimination of single-use plastic by 2020 is perfectly fine, but a total ban on plastic will cause harm for both industry and the common man.
  • The proposed ban in Tamil Nadu would hit over 5,000 plastic industries across the State and investment close to Rs 3,000 crore turning idle.
  • Tamil Nadu would incur an annual loss of around Rs 18000 crore.

Experts say that it is not the plastics which have become a problem. It is the way in which human beings deal with disposable plastics is the real cause for concern. It is only the disposable kind that harms the environment.

Way Ahead

Experts suggest way ahead through the change in attitude which is possible through knowledge and information dissipation. They suggest productive use of budget allocation towards advertisements to stop plastic by setting up centres for the collection of plastic bags.

Indonesia hit by Volcanic Tsunami

On 22nd December 2018, Indonesia was hit by a Tsunami. As the giant tsunami waves crashed into coastal towns on the islands of Sumatra and Java, at least 281 people were killed and 1,016 were injured.

About Tsunami

Tsunami refers to a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.

Tsunamis are different from the normal sea waves. Normal waves are generated due to the wind and Tides are generated due to the gravitational pull of the Moon and the Sun, whereas Tsunami is generated by an abrupt movement on the ocean floor due to the triggering points like Earthquakes, volcanic eruptions, underwater explosions, landslides, glacier calving or meteorite impacts.

Tsunami waves have a large wavelength in the open ocean. As the Tsunami waves reach shallow water near shores they grow rapidly in size and make a landfall causing large-scale destruction.

Volcanic Tsunami of Indonesia

The Tsunami which Indonesia witnessed on 22nd December is attributed to the collapse in the west-southwest flank of the Anak Krakatau volcano. The collapse resulted in millions of tonnes of rocky debris plunging into the sea. This resulted in the displacement of large volumes of water resulting in Tsunami waves.

Anak Krakatau

Indonesia lies on the Pacific ring of fire. This makes Indonesia vulnerable to earthquakes. Indonesia also houses 127 active volcanoes and one of these volcanoes is the Anak Krakatau.

Anak Krakatau is a volcanic island formed in 1927 after the Krakatoa volcano eruption. The Anak Krakatau was erupting from June 2018. The authorities have warned that there can be an eruption again and have advised people to stay away from the coast for a while.

Ring of Fire

Ring of Fire is an area in the Pacific Ocean where earthquakes and volcanic eruptions are frequent. The Ring of Fire is a direct result of the movement and collisions of lithospheric plates of the earth.
