I forgot to include the very last sentences of the day. Thank you very much.

1) Every week a person in Britain uses three plastic bags. They are strong and don’t disappear. They can last hundreds, possibly thousands of years. 2)They are called white pollution in China. In Dhaka, the capital of Bangladesh, 10,000 plastic bags were thrown away every day.
3) An environmental expert explained the reporter that things were getting better since the government had banned plastic bags.
4) Plastic bags had been a problem in Ireland too until the bag tax was introduced. People pay 10 pence for each plastic bag they use.
5) A new biodegradable plastic bag was introduced in 2002. If it is put in the ground, it disappears after 18 months.
6) Alternatives to plastic bags are cardboard boxes or paper shopping bags. If you use plastic bags, use it five or six times or ask if they are biodegradable.

Everything reads fine except this:

"...explained the reporter that things..."
You need to add "to" after "explained."

1) In Britain, it is estimated that a person uses three plastic bags every week. These bags are known to be durable and have a long lifespan, potentially lasting for hundreds or even thousands of years. This contributes to the issue of plastic pollution.

2) In China, these plastic bags are referred to as "white pollution." Dhaka, the capital of Bangladesh, faces a significant problem with plastic bag waste, with approximately 10,000 bags being discarded daily.

3) According to an environmental expert, there has been some improvement in the situation due to the government's decision to ban plastic bags. This suggests that the ban has helped reduce the usage and disposal of plastic bags, leading to a positive environmental impact.

4) Ireland also faced challenges with plastic bags until a bag tax was introduced. Under this system, individuals are required to pay a fee of 10 pence for each plastic bag they use. This tax has incentivized people to decrease their reliance on plastic bags.

5) In 2002, a new type of biodegradable plastic bag was introduced. When disposed of properly and placed in the ground, this bag has the capability to decompose within 18 months. This technological advancement offers a more environmentally friendly alternative to traditional plastic bags.

6) If you prefer alternatives to plastic bags, cardboard boxes or paper shopping bags can be viable options. However, if you do use plastic bags, try to reuse them multiple times before discarding them, or consider using biodegradable bags if they are available. This will help minimize the negative impact on the environment.
