One major need of humans is food and every day food sources bdecome lesreases.

Some insects have been consumed in different cultures for centuries and are known to be rich in protein.

There has been reports and researches about edible insects and their consumption.

Some scientists believe that meat production and consumption causes environmental problems and world's current ressources will not be able to feed the whole population in the future t. Therefore, people should replace them with more sustainable and durable options of protein.

Insects such as cockroaches are rich in protein and can live in almost any circumstances even after nuclear explotsions.

Therefore, they are a good alternative for regular protein sources such as chicken and fish.

Although insects are rich in nutritionsents, they also harm the environment and and affect the food chain negatively.

If a country decides to consume insects as foods, the government should regulate them carefully or do it itselfregulate by themselves in order to prevent the overpopulation of the insects.

I hope this is what you mean

Insect consumption may startedhappen due to the lack of food in these countries and becoame a cultural habit.

In my point of view, they are not really appealing and may cause some digestion problems.

Point of view = opinion

If there would bare no other options, they are good alternatives but for now I do not see an urgency to consume insects as food ressources t. Therefore, I will not recommend them to do so.

One major need of humans is food and every day, food sources bdecome lessrease.

Instead of using 'become less', you would use decrease.
If you are saying that food sources decrease every day, you would need a comma for clarity.

Some people believe that in order to requiremeet the needs of the food for the population, countries should consider insects as food ressources.

Use 'meet' instead of 'require' because you're referring to reaching a goal.
Ressources -----> Resources.

Some insects have been consumed in different cultures for centuries and are known to be rich in protein.

Added in 'are' as a verb.

There hasve been reports and researchs conducted about edible insects and their consumption.

Changed 'has' to 'have' because it's past tense plural.
Added 'conducted' as the verb.
Researchs ----> Research (it stays the same for singular and plural)

Some scientists believe that meat production and consumption causes environmental problems and the world's current ressources will not be able to feed the whole population in the future therefore people should replace them with more sustainable and durable options of proteinprotein sources.

Added in 'the' in front of 'world' as a definite article.
'Durable' is used to describe things that don't break easily. You could use 'eco-friendly' instead.
Word order.
Changed options to sources.

Therefore, they are a good alternative for regular protein sources such as chicken and fish.

Comma after 'therefore'.

Although insects are rich in nutritionsents, they also harm the environment and and affect the food chain negatively.

'Nutritions' ----> 'Nutrients'.

If a country decides to consume insects as foods, the government should regulate them carefully or do it itself in order to prevent the overpopulation of the insects.

'Foods' -----> 'Food'
'Do it itself' was a bit unclear so I changed it.

In sSouth Asian countries such as Thailand and India, insects are common street food with huge consumption even though their not-so-charming appearance.

'South' - capitalised.
'Apperance' ----> 'Appearance'.

Insect consumption may have started due to the lack of food in these countries and so it becoame a cultural habit.

'Have' for the verb.
Added 'the' as an article.
'So it' makes the sentence flow.
'Become' ---> 'Became'.

In my view, they're not really appealing and may cause some digestion problems.

'They' ---> 'They're'. Contracted verb.

If there would beis no other option, they are good alternatives b. But for now, I do not see an urgency to consume insects as food ressources therefore willI would not recommend ito do so.

Commas.
Made the sentence shorter.
