You are advised to use eco-friendly appliances like refrigerators and a.c. explain giving reasons how these appliances causing harm to our environment

Refrigerator and air conditioning system have refrigerants known to cause ozone layer depletion thereby climate change. In history, Chlorofluorocarbon or CFC and hydrochlorofluorocarbons HFCF are used as a refrigerant which is known to have a role in ozone depletion. The inefficient appliances will also incur high electricity usage. High electricity is to equal high coal or diesel consumption thus high carbon footprint.

Let us assume that the funnel is also made of protein, now thermodynamic state changes in the protein structure causes the peptide bonds between the proteins to denature and change losing their strength and conformation this change in conformation would result in the funnel itself to lose its shape, it could have extra grooves form within it or it could break away completely dissociating the ionic bonds that holds the polypeptides together as the tertiary structure of a protein molecule also has secondary interactions such as sulfhydryl bridges and hydrogen bonds which keep the 3d structure which also be disrupted.
