Vol. 1 No. 2 (2021): Segundo número

We are pleased to present this issue, which contains a study on beets, an agricultural product of important consumption and the lead contamination to which it may be subjected; this being an important contribution to the knowledge of environmental quality.
Biodiversity is present in this publication, through an analysis of a latent problem in our national reality, which needs to be solved technically and politically, such as the search for land for cultivation versus the conservation of our biodiversity.
In the same line, we present a valuable contribution to identify the factors that mainly affect one of the most recurrent forms of erosion in our country, such as water erosion.
Finally, two articles related to fundamental aspects of human health; a study on the determination of the so valuable vitamin C in citrus fruits and a research where the ever present need for blood donation is analyzed within the context of the severe COVID 19 pandemic.
Our journal Ciencia y Practica thanks the authors who have collaborated in this issue for their valuable contribution to our society.
