How mining secures the Bitcoin network
Mining is critical, essential, and one of the mechanisms the Bitcoin system uses to implement transactions and save them onto the blockchain. Proof of Work, PoW, is the consensus criterion that will allow the competing miners to achieve higher levels of operations (high rates of computation) on solving hard puzzles. Upon correct solutions of the hard math problems, much energy is consumed in the form of computation, and therefore on committing enough energy any number of such available people can do it. Nonetheless, upon reaching a consensus on the problem's solution, it is checked by other miners, and the corresponding set of transactions is filled into block and then added to the blockchain by other miners. This is opposed to the revision of the sequence of past transactions, which requires society due to the chain correctness principle very high computational equipment.
Besides being an input into the transaction confirmation, mining also solves the problem of double-spending where one Bitcoin can be used more than once in a transaction. This means that miners make sure verification of transactions is done by a majority of the nodes and better ensure that only rightful transactions are included in the blockchain. This in turn upholds the trust of individuals in a decentralized bitcoin system.
The miners receive rewards by earning the blocks with newly created Bitcoin, this in turn serves as an inducement for mining in order to defend the security of the system. Later the number of Bitcoins that can be created will drop as the cap of 21 million bitcoins is not increasing, it is anticipated that increased transaction fees will be increased if this ratio is actualized. This is to say that mining of Bitcoin came to alleviate concerns about the security of Bitcoins, validates them, makes them inviolable, makes them difficult to attack, and transfers them in such a way that no one entity is in total control.

The major concern about the mining in the crypto space is most time the environmental impact they have
